I've tried searching this, and it seems like the answer is no, but I wanted to ask it again:
Can you hold on to a feat until a later level?
The reason that I ask this is because I am playing an unchained summoner, with a focus on improving my Eidolon to the max. To this end, I am putting as may feat slots toward Extra Evolution as I can. You can take that feat at levels 1, 5, 10, 15, and 20. The problem is that level 20 one. As an unchained summoner, I do not get a feat slot at level 20, so there is no way to actually take the feat at that level, unless I hold onto a feat slot. I know there are retraining rules, but is that the only way to do this? It seems like a bit of an oversight.
